5/12x-1/2y=-61/6
\n" ); document.write( "LCD=12. Multiply equation bty 12
\n" ); document.write( "5x-6y=-122.....................1
\n" ); document.write( " 1/5x-1/3y=-167/15
\n" ); document.write( "LCD = 15
\n" ); document.write( "3x-5y=-167......................2
\n" ); document.write( "5 x -6 y = -122 .............1
\n" ); document.write( "3 x -5 y = -167 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by -5
\n" ); document.write( "Multiply (2) by 6
\n" ); document.write( "-25 x + 30 y = 610
\n" ); document.write( "18 x + -30 y = -1002
\n" ); document.write( "Add the two equations
\n" ); document.write( "-7x=-392
\n" ); document.write( "/ -7
\n" ); document.write( "x = 56 = 56.00
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "5 x + -6 y = -122
\n" ); document.write( "280 + -6 y = -122
\n" ); document.write( " -6 y = -122-280
\n" ); document.write( " -6 y = -402
\n" ); document.write( " y = 67 \n" ); document.write( "

\n" );
